Recent advances in silica-alumina refractory: A review

In this article, the elaboration and the characterization of silica-alumina refractory have been reviewed. Refractory oxides encompass a broad range of unary, binary, and ternary ceramic compounds that can be used in structural, insulating, and other applications. This paper provides a historical

Constituent Materials of Concrete - InterNACHI

Concrete is a composite material consisting of a binder, which is typically cement, rough and fine aggregates, which are usually stone and sand, and water. These comprise the constituent materials of concrete. But because of the many variables of the raw materials and how they are processed and

The effect of particle sizes and solids J concentration on the rheology of silica sand based suspensions

The effect of particle size and solids concentration the effect of particle size was evaluated on three different particle size fractions of silica sand with d50 values of 90, 180 and 300 microns. These slurries with relatively coarse particles are a representation of what is .
